Infusionssystemen

Infusionssystemen, or infusion systems, are devices and accessories used to deliver fluids, medications, or nutrition to patients, typically via intravenous routes but also by enteral or other delivery methods. They are designed to provide accurate dosing, controlled delivery rates, and safe administration of therapeutic agents.

A typical infusion system includes a container (IV bag or bottle), a spike, a drip chamber, tubing, and connectors. A flow regulator or pump controls the rate, with extensions and back-check valves common in some setups. Infusion pumps—volumetric, syringe, and patient-controlled devices—offer precise, programmable dosing. Gravity-driven setups rely on height and tubing resistance, while pump-based systems provide higher accuracy. Enteral feeding pumps deliver nutrition through a tube using a similar mechanism.

Safety and regulatory features are central. Alarms for occlusions and air in the line, anti-free-flow protection, and dose-error reduction help prevent adverse events. Consumables are typically sterile and designed for single use or limited reuse, with compliance to regulatory standards such as CE marking or FDA approval depending on the market. Material compatibility with drugs and fluids is required to avoid interactions or leaching.

Infusionssystemen are used in hospitals, clinics, and home care for hydration, antibiotics, chemotherapy, parenteral nutrition, blood transfusions, and other therapies. Proper selection, installation, and maintenance are essential to ensure safe therapy delivery.
